Special nut with square profile (pair set)

thingiverse

I was in urgent need of a completely plastic nut with a square profile that could hold its own against heavy loads.\nTaking inspiration from multiple designs and combining their best features, I successfully created an ideal couple that perfectly met my requirements.\nMy gratitude is reserved for the original designers who came up with these brilliant concepts:\nThe pipe wrench nut design was found here https://grabcad.com/library/pipe-wrench-1\ncollet clamping nut can be seen in this model https://grabcad.com/library/er11-a-type-collet-clamping-nut-1\nThe final design is engineered to fit my two-armed 3D printing device (biggest holes have a diameter of 21 mm), as showcased here:http://www.thingiverse.com/thing:1167051http://www.thingiverse.com/thing:1167238\nCombining all the pieces should result in this fully functional lamphttp://www.thingiverse.com/thing:319339\nI hope you enjoy this outcome.
